Then when mounted without the softdep option it would have to clear the softdep bit before mounting read/write.

Another interesting tweak would be adding the linux -loopback option to get mount to attempt to autoconfigure a vn device. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
